• Rules. Washington's dangerous waste (DW) treatment rules include the federal requirements and the state's more stringent rules, which apply to facility permit application process, treatment facility design, construction and operation, and on-site treatment by large quantity generators (LQGs), medium quantity generators (MQGs), and small quantity generators (SQGs).
Washington has established a waste management hierarchy that encourages waste reduction and recycling over treatment or disposal of wastes. Refer to the state section POLLUTION PREVENTION
